The Community of Christ (formerly RLDS), has more sections to their Doctrine and Covenants –163 sections. This is 25 more than what's in the LDS Doctrine and Covenants.
I notice also that many of the scriptures from sections written by Joseph Smith have been omitted by the Community of Christ.
Without creating a long list answer, can someone explain what's in the RLDS D&C that isn't in the LDS D&C? And what the RLDS have removed or changed from the D&C that Joseph Smith wrote?
